The large-scale nanostructures were fabricated by laser interference lithography technique. The detecting optical signal-extinction spectra of the system were monitored by UV-visible spectrophotometry. The 3D finite-difference time-domain simulation was used to observe the plasmonic interaction of the sensing system. The platform exhibits an exceptionally large turn-on signal by a 120 nm red shift of the localized surface plasmonic resonance peak, results in the limit detection of 140 pM. The centimeter-scale localized surface plasmon resonance nanostructures combined with turn-on design scheme would offer a promising sensor-on-chip biosensing platform.</p></abstract><trans-abstract xml:lang="ru"><p>Мы представляем плазмонный биосенсорный анализ включения для обнаружения инсулина с помощью аптамерной ДНК, основанный на плазмонном взаимодействии двухслойных массивов нанодисков золота и серебра сантиметрового масштаба и наночастиц золота. Крупномасштабные наноструктуры были изготовлены методом лазерной интерференционной литографии. Детектирующий оптический сигнал - спектры экстинкции системы контролировались методом УФ-видимой спектрофотометрии. Трехмерное моделирование во временной области с конечной разностью использовалось для наблюдения за плазмонным взаимодействием сенсорной системы. Платформа демонстрирует исключительно большой сигнал включения за счет красного смещения на 120 нм пика локализованного поверхностного плазмонного резонанса, что приводит к пределу обнаружения 140 пМ. Наноструктуры локализованного поверхностного плазмонного резонанса сантиметрового масштаба в сочетании со схемой включения могут предложить многообещающую биосенсорную платформу «сенсор на кристалле».</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инсулиночувствительность</kwd><kwd>локализованный поверхностный плазмон</kwd><kwd>плазмонное взаимодействие</kwd><kwd>наноструктура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>insulin sensing</kwd><kwd>localized surface plasmon</kwd><kwd>plasmonic interaction</kwd><kwd>nanostructure</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research is funded by Hanoi University of Science and Technology (HUST) under project number T2022-PC-083.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Morris A.
